The Itakpe Iron Ore Mine was divided into four benches; 241 - 258 m, 263 - 275 m, 276 - 286 m and 308 - 312 m. Joints along the discontinuities were mapped. The data obtained were analyzed using ...
Here, we provide new evidence that supports subaerial volcanic eruptions in magmatic arcs as a viable process for the accumulation of metals at or near the surface by focusing on the world …
Potassium radioactivity in the Earth's core has been a topic of discussion for nearly four decades. Purely on geochemical grounds, Hall and Murthy and Lewis proposed that K enters the metallic core of the Earth as a consequence of the presence of sulfur in the core (Murthy and Hall 1970).Since then, the implications of K in the Earth's core for …

The current study looked at the concentration of naturally occurring radioactivity and radiation hazards in iron ore deposited in soil. The aim of this study was to identify the dose of radiation which is emitted from rocks, soil and some building materials, the radiation dose and the effect in the area. In this work, analyses of the …
The domestic iron and steel, sponge iron, ferrous alloys, and alloy steel sectors consume about 47% of the total output. Iron ore exports totaled 29.5 million metric tonnes during the years 1999 and 2000, with China and Japan each receiving 22% and 50% of such shipments, respectively. The iron and steel sector is rapidly expanding in India …
The ore contains a small percentage of rare earths, but other minerals are removed through flotation, magnetic or electrostatic processing to produce a mixed rare earth concentrate that often ...
(Updated April 2020) Radioactive materials which occur naturally and where human activities increase the exposure of people to ionising radiation are known by the acronym 'NORM'. NORM results from …
Iron ore can be mined at level 15 Mining providing 35 Mining experience. After an iron rock is mined, it will respawn in 5.4 seconds. Iron ore is used to smelt iron bars and can be smelted with coal to make steel bars. Smelting iron ore into iron bars has a 50% success rate, unless the player is wearing a ring of forging, using superheat item, or using the …
The raw iron ore used by a Chinese iron beneficiation plant is accompanied by radioactive elements [1]. The beneficiation process adopts the conventional two-stage crushing, two-stage grinding s...

Itakpe iron ore mine situated within longitude 6 016 E and latitude 7 36 0N and 7 39 N of the equator (Fig. 1)is among the largest reserves in Nigeria and ranked as one of the best in the world having estimated reserves of 3 billion tonnes of ore [5]. The adjoining settlements are mainly agrarian depending on subsistence farming for their ...
Definition. Radioactivity in minerals are caused by the inclusion of naturally-occurring radioactive elements in the mineral's composition. The degree of radioactivity is dependent on the concentration and isotope present in the mineral. For the most part, minerals that contain potassium ( K ), uranium ( U ), and thorium ( Th ) are radioactive.

Anomalous radioactivity was encountered in the Athabasca Sandstone at the unconformity with radioactivity of 333 cps over 3.4 m including 644 cps over 0.3 with a radioactive peak of 771 cps.
The other day i was hiking and came upon an old abandoned iron ore mine in new jersey. on the ground were some kind of metalic tailings sort of gold in color. I was wondering when iror ore was mined and dug up was it also mixed with things like uranium. My real question is could small scraps of uranium be mixed in with all the iron tailings ...
Price - Chart - Historical Data - News. Prices for iron ore cargoes with a 62% iron ore content rebounded to $105 per tonne after touching a 16-month low of $100 on April 4th, as markets increased their bets of higher demand from Chinese steel producers. Industry groups noted that the large volumes of stimulus from Beijing supported margins for ...
In the present paper the gamma spectrometric technique has been used to study the natural radioactivity levels present in the iron ore samples collected from the Sandur of Karnataka, India. This region, a member of Dharwar craton, known as Sandur schist belt is rich in Manganese and Hematite ore (Fe). The entire belt is characterized …
Radioactive rocks were front and center during the late 1940s and early 1950s, as Colorado, Utah, and New Mexico hosted what was called the "Great Uranium Rush," the last mineral rush in which individual prospectors had a chance to strike it rich. The quest was for, in the parlance of that era, "hot rocks"— rocks emitting elevated levels …
The field radiometric and laboratory measurements were performed at the Sin Quyen copper deposit in North Vietnam. The field gamma-ray spectrometry indicated the concentration of uranium ranging from 5.5 to 87 ppm, thorium from 5.6 to 33.2 ppm, and potassium from 0.3 to 4.7%. The measured dose rates ranged from 115 to 582 nGy/h, …
